They have data type just like variables, for example an integer type pointer can hold the address of an integer variable and an character type pointer can hold the address of char variable. If you declare int *ptr, **ptr1;, then ptr1 has type "pointer to int *" and thus can point to ptr. But in C# pointer can only be declared to hold the memory address of value types and arrays. We need to store address of integer variable to integer pointer. Question 4. True. A pointer variable is a variable that contains an address, usually the address of another variable.

The body of your question asks whether "a pointer is a data type or not". B. B. change within a function. The general form of a pointer variable declaration is â type *var-name; Here, type is the pointer's base type; it must be a valid C data type and var-name is the name of the pointer variable. A pointer is also called reference type variable in generic way.int *pa = &a; can be stated like pa is a pointer to an integer.pa points to a.Just like a has a content (55), pa has a content (that's the address of a).As pa itself is a variable, it has an address too..
